166 Appendix A WLAN Application Gateway 2246• User Time Period—the length of time (in seconds) that statisticsaccumulate in the Userpkts column before resetting to zero. Whentroubleshooting a problem, use this setting to isolate statistics for a giventime period (for example, one hour). This is the only field in this screenthat can be changed by the user.The rest of the display is a table of Ethernet statistics. The Pkts and UserPkts columns list the count of Ethernet packets received or transmitted.The Bytes column is the count of bytes received or transmitted during theamount of time indicated by the Stats Time Period.• RX—number of packets and bytes received addressed to the WLANApplication Gateway 2246.• RX Broadcast—the number of broadcast packets and bytes received.• RX Multicast—the number of packets and bytes received with themulticast address. (A multicast message is sent to more than onedestination on the network.)• RX Not For Us—the number of multicast packets and bytes receivedthat were not for the WLAN Application Gateway 2246.• TX—the total number of packets and bytes transmitted.• Interrupts—the number of times the Ethernet controller signals themicroprocessor that it has received or sent a packet.• Collisions—the number of times the Ethernet controller attempts tosend a packet, but another device on the network transmitted at thesame time, corrupting the transmission.• Collision Drops—the number of packets the Ethernet controllerdiscards, because there were over sixteen collisions. After sixteencollisions, the Ethernet controller hardware discards the current packetand attempts to send the next packet in its buffer.• CRC Errors—the number of packets discarded by the Ethernetcontroller, because of a Cyclic Redundancy Check (CRC) error.Viewing the network statusFrom the System Status Menu screen, select Network Status.The Network Status screen displays information about the Ethernet network.This information can help troubleshoot network problems.Software versionsEach WLAN Application Gateway 2246 and handset runs software thatis controlled and maintained through versioning.
